I just found refurbished one for 250 EUR. very capable hardware, bang and olufsen spekaers, some led ring light, some touch playback controls and even hdmi in and 12" usb c touch screen. Since I am new to all this, and I plan to use this pc as a HA server, is there a way to utilize those leds and hdmi and touch playback buttons directly as entities or similar? I am not sure how HA talks to funky peripherals directly on the server it is running on.
